100 help
101 This can be used to adjust the minimum FCK/PCK ratio.
102
103 With this you can make sure that DISPC FCK is at least
104 n x PCK. Video plane scaling requires higher FCK than
105 normally.
106
107 If this is set to 0, there's no extra constraint on the
108 DISPC FCK. However, the FCK will at minimum be
109 2xPCK (if active matrix) or 3xPCK (if passive matrix).
110
111 Max FCK is 173MHz, so this doesn't work if your PCK
112 is very high.
